ABSTRACT:
A method of preventing a flow pattern in a wet-type color image forming apparatus and a system adopting the same includes a material layer directly contacting a developing roller of a developing unit of a photosensitive body of the image forming apparatus and having a thickness of 7–15 μm. A size of an essential composition used for representing corresponding one of colors in high-concentration ink is 0.7–1.5 μm. A hold up volume is not formed between the developing roller and the photosensitive body during a developing process, and a flow pattern such as a stripe, is not formed in a final image, and even though the flow pattern is formed in the final image, the flow pattern can be minimized.
